我目前正在为一个学校项目制作一款基于文本的游戏。我唯一的问题是，当用户输入不包括"Take"和[项目名称]时，我无法让我的程序打印"无效输入"。因此，只要用户输入"Take"，该物品就会被添加到库存中。

我试着把这个添加到我的代码中，但它仍然只接受'Take'作为用户输入。
# invalid command
elif ('Take'+item) not in user_input:
print('Invalid inputn')
这是您期望的操作方式。我在公司里做了一些改变。我已经删除了你所有的"自动大写"，所以你必须准确地输入命令。我已经删除了所有的递归调用，并将它们替换为循环——这不是递归的正确使用。
我也删除了你的块标题，因为我不想处理字符集。你可以把它加回去。

要验证Take + Items，您需要读取输入并存储它们，如果我理解正确的话，如下所示。
# Check for Take in input and Item name
elif 'Take' in user_input:
item = user_input[5:]
if item in rooms[current_room].values():
inventory.append(item)
print('You have added {} to your inventory.'.format(item))
print('<>' * 50)
else:
print('You can't take that!')
print('<>' * 50)```
